Question
1. Simple sugars are defined as polyhydroxy aldehydes/ketones. All carbons except one have an
OH group. The remaining carbon has a double bond to oxygen, making it an aldehyde or
ketone. For example, the Fisher projection of glucose looks like this:
C

-HO-
CH2OH
Because a simple sugar has both a carbonyl carbon and built-in nucleophiles, a reaction can
occur within the molecule itself to create the hemi-acetal form of the sugar. Propose a mechanism for
this reaction when it occurs in an aqueous solution.
